As a new slot card collector, I have a few questions that I'm hoping some of you old pro's can answer...

Do most slot card collectors value blank cards over cards with names on them?

Do many slot card collectors collect variations that are caused by the way a name is printed on a card? For example, if a casino silkscreens the names on some cards, but then switches to embossing the names in raised letters, will most collectors want one of each?
